A Comparison between Mass-losing and Standard Solar Models

摘要: The effects of main-sequence mass loss on the evolution, interior structure, and surface composition sun are studied. Modeling results presented for three mass-losing solar models initial two solar, plus a standard one comparison model. It is shown that can be evolved to produce present-day do not differ radically in structure from models. require low He-4 abundances predict high He-3 near limits, yet still within bounds, observational estimates. have somewhat higher B-8 neutrino fluxes, but also fail reproduce observations by wide margin. For models, protosolar Li Be completely destroyed, requiring mechanism partial replenishment observed abundances. 34 references.
